It seems to have fixed the problem with recording audio distorted. But, when UMC ASIO driver is selected, recording audio works but there's no playback... i think its trying to use a speaker somewhere I dont have one plugged in when I do that... But when ASIO4ALL v2 is selected, I can hear it, but not record...
I also tried all the available output options for UMC ASIO
Hopefully you have powered monitors or headphones connected to your Behringer interface... Yes, No?
Also are you using Windows 10, and if so, when you click on the little speaker icon (on the task bar), does it show your Behringer interface as being selected and at 100%?
